At 6-foot-6 and 285 pounds, McDermott has ideal size for a major college offensive tackle prospect. He's long and has the frame to add a lot more weight at the college level.
Athletically, he's very impressive. He has tremendous footwork, balance, and explosiveness. He's very nimble on his feet, and he can get to the second level with relative ease. He has the type of natural athleticism that will enable him to play left tackle at the college level. Anytime you get a kid who can legitimately play left tackle, it's a major plus since he'll also be able to handle playing right tackle, or both guard positions. That's part of the reason why left tackles are so rare.
From an intangible standpoint, McDermott brings a lot to the table as a prospect as well. He's known for a strong work ethic, much like his older brothers (Shane and Tyler). He knows the game of football very well. He's been around it his entire life. His father, Randy, played college football. His older brother, Tyler, played at Colorado State. And now Shane is Miami's starting center. Kc has a very good football IQ and should be able to come in and pick things up pretty quickly.
McDermott chose Miami over Notre Dame in the end. The Irish hung in there because Tyler is now a graduate assistant on Brian Kelly's staff there. In the end, however, his heart was at Miami.
McDermott becomes Miami's third offensive line commitment in the 2014 class. He joins four-star Trevor Darling, a 6-foot-6 tackle prospect from Miami Central, and center Nick Linder (Brandon's younger brother). That's a very strong offensive line class, one that could end up being one of the best in the entire country.
